In a large mixing bowl, combine the shredded chicken, shredded cheddar cheese, black beans, diced bell pepper, and taco seasoning. Mix until well combined.

Heat a skillet or frying pan over medium heat and add a little olive oil.

Place one tortilla in the skillet and spread a quarter of the chicken mixture on one half of the tortilla. Fold the other half over the filling.

Cook for about 3-4 minutes on one side until golden brown. Carefully flip the quesadilla using a spatula and cook for another 3-4 minutes on the other side until the cheese is melted and the tortilla is golden brown.

Remove the quesadilla from the skillet and let it sit for a minute. Then cut it into wedges.

Repeat steps 3-5 for the remaining tortillas and filling.

Serve warm with salsa and sour cream if desired.

Feel free to customize the filling by adding other vegetables like corn or mushrooms.

You can substitute other types of cheese based on your kids' preferences.

These quesadillas can be made ahead and reheated for a quick meal.
